三、修改文字样式

1，修改字体大小

var doc = new jsPDF();

//字体大小1(默认样式)

doc.text(20, 20, '1: Welcome to hangge.com');

//字体大小2

doc.setFontSize(18);

doc.text(20, 30, '2: Welcome to hangge.com');

//字体大小3

doc.setFontSize(22);

doc.text(20, 40, '3: Welcome to hangge.com');

doc.save('Test.pdf');

2，修改文字颜色

var doc = new jsPDF();

//文字颜色1(默认样式)

doc.text(20, 20, '1: Welcome to hangge.com');

//文字颜色2

doc.setTextColor(150);

doc.text(20, 30, '2: Welcome to hangge.com');

//文字颜色3

doc.setTextColor(0,0,255);

doc.text(20, 40, '3: Welcome to hangge.com');

doc.save('Test.pdf');

3，修改字体样式

var doc = new jsPDF();

//字体样式1(默认样式)

doc.text(20, 20, '1: Welcome to hangge.com');

//字体样式2

doc.setFont("courier");

doc.setFontType("normal");

doc.text(20, 30, '2: Welcome to hangge.com');

//字体样式3

doc.setFont("times");

doc.setFontType("italic");

doc.text(20, 40, '3: Welcome to hangge.com');

//字体样式4

doc.setFont("helvetica");

doc.setFontType("bold");

doc.text(20, 50, '4: Welcome to hangge.com');

//字体样式5

doc.setFont("courier");

doc.setFontType("bolditalic");

doc.text(20, 60, '5: Welcome to hangge.com');

doc.save('Test.pdf');

4，文字旋转

var doc = new jsPDF();

//默认样式不选旋转

doc.text(20, 20, '1: Welcome to hangge.com');

//旋转45度

doc.text(20, 80, '2: Welcome to hangge.com', 45);

//旋转90度

doc.text(120, 80, '3: Welcome to hangge.com', 90);

doc.save('Test.pdf');

5，文字换行显示

(1)我们使用换行符(\r)可以手动让文字换行。

var doc = new jsPDF();

doc.text(20, 20, 'Welcome to hangge.com.\rWelcome to hangge.com.\rWelcome to hangge.com.');

doc.save('Test.pdf');

(2)默认情况下，文字超过页面宽度时默认是不会自动换行的，我们可以通过其内置的方法将文字自动拆成多行再渲染。

var doc = new jsPDF('p','in','letter');

var sizes = [12, 16, 20];

var fonts = [['Times','Roman'],['Helvetica',''], ['Times','Italic']];

var verticalOffset = 0.5;

var words = 'Welcome to hangge.com. Welcome to hangge.com. Welcome to hangge.com.'

for (var i in fonts){

if (fonts.hasOwnProperty(i)) {

var font = fonts[i]

var size = sizes[i]

//将文字自动换行显示

lines = doc.setFont(font[0], font[1])

.setFontSize(size)

.splitTextToSize(words, 7.5)

doc.text(0.5, verticalOffset + size / 72, lines)

verticalOffset += (lines.length + 0.5) * size / 72

}

}

doc.save('Test.pdf');

6，文字对齐方式

var doc = new jsPDF('p', 'pt', 'letter');

doc.text( '1: This text is normally\raligned.', 140, 50 );

doc.text( '2: This text is centered\raround\rthis point.', 140, 120, 'center' );

doc.text( '3: This text is rotated\rand centered around\rthis point.', 140, 300, 45, 'center' );

doc.text( '4: This text is\raligned to the\rright.', 140, 400, 'right' );

doc.text( '5: This text is\raligned to the\rright.', 140, 550, 45, 'right' );

doc.text( '6: This single line is centered', 460, 50, 'center' );

doc.text( '7: This right aligned text\r\rhas an empty line.', 460, 200, 'right' );

doc.save('Test.pdf');
