Javascript string issue because of string strip operation of uliweb template

[zhangchunlin]

example code below
in the line: ' ref="input"' ,if the space char removed, javascript will treat '[return]r' as '\r'

Can reproduce with this static file test.zip can run server with "python -mSimpleHTTPServer" in the directory

Vue.component('currency-input', {
  template: '\
    <span>\
      $\
      <input\
        ref="input"\
        v-bind:value="value"\
        v-on:input="updateValue($event.target.value)"\
      >\
    </span>\
  ',
  props: ['value'],
  methods: {
    // 不是直接更新值，而是使用此方法来对输入值进行格式化和位数限制
    updateValue: function (value) {
      var formattedValue = value
        // 删除两侧的空格符
        .trim()
        // 保留 2 位小数
        .slice(
          0,
          value.indexOf('.') === -1
            ? value.length
            : value.indexOf('.') + 3
        )
      // 如果值尚不合规，则手动覆盖为合规的值
      if (formattedValue !== value) {
        this.$refs.input.value = formattedValue
      }
      // 通过 input 事件带出数值
      this.$emit('input', Number(formattedValue))
    }
  }
})
